Mobile Devices Destroying Our Eyesight

from the see-what-now? dept

Last week, while traveling around Washington DC, someone asked me how I could possibly read the screen on the mobile device I was using. It never really seemed that difficult, but apparently I (and many others) are doing quite a bit of damage to our eyes. At least that's what a new article is claiming, saying that the nation's obsession with reading things on mobile devices is generating new levels of eye strain, going beyond the typical eye strain found by people who are simply staring at a computer screen all day. To blame, of course, is the tiny text combined with the quality of the screens. Apparently, doctors are finding that people are coming in and asking for prescription glasses just for the sake of reading email on their Blackberry devices. This isn't the first time, of course, that mobile devices have been called out for creating potential health problems. We've already heard too many stories about texter's thumb, for instance. However, the "good" news is that companies are working on ways to deal with this, by making the text more readable -- though, it still seems like we're far away from a real shift in how people view content on a small screen. A few years ago at the DEMO conference, there was a great demo from the company F-Origin showing a system that used motion sensors to let you view content on a mobile device screen as if it were simply a lens on a full-sized screen. It looked like a really powerful solution, that could help address this issue, but it's not clear that it's gone anywhere since then.

I have no scientific evidence but I just find it hard to believe that our eyes are damaged by tiny text whether in a book, laptop screen, or a Blackberry. Peoples' ability to focus declines with age, particularly around age 40 which, coincidentally, is when they have had a number of years in front of such devices. In my case I had perfect vision until I stared at a computer all day for 18 years. I could also say, I had perfect vision until I reached age 40.

odd

*gasp*

Oh no! People are asking for glasses so they can see things that may be smaller than they wanted to bother with before!

Next you'll tell me that snipers are ruining their eyesight as evidenced by the fact that they want scopes on their rifles.

And astronomers are in serious trouble -- they keep requesting these huge telescopes to see things that are further away -- incontrovertable evidence that astronomy ruins your eyes! Telescope sales prove it!

The fact that people want glasses that allow them to read tiny text doesn't mean they're ruining their eyes. Perhaps it means that they're realizing that their eyes aren't as good as they used to be as they get older. Or they already knew that but didn't care because they didn't have any reason to bother correcting it.

Eyesight

How in the world does wanting to read microscopic text and needing reading glasses for that translate to mobile devices damaging eyesight? Perhaps these people need psychological counseling for needing to be that "connected"!!

Eye Strain

doesn't necessarily cause poor vision, it just makes your eyes tired and your head ache. Looking at small text is no more damaging to your eyes than listening to faint sounds wuld be damaging to your hearing.

Whne your head starts to ache and your neck gets stiff from holding still for too long, take a break.

It makes total sense

There are two ways your eyes focus: One is your inherent optical structure -- the lens and its relationship with the retina. The other is your musculature that works to focus your eyes, and makes up for inherent deficiencies. Work those muscles a lot and you get "eye strain" and they cannot make up so much for the optics, and you have vision problems.

That's why using these devices can cause this. Normally people need glasses as they get older. Eye strain like what's described is just bringing that need for glasses that might not come until one's 40s a whole lot earlier.

(Learned from my optometrist. I could be wrong.)

Of course, there's the aggravating factor of the EM signal baking microbubbles into your eyeballs, but we're not supposed to discuss that.

Oh, and people don't tend to get it so much from tv because tv is very low resolution, so there's not much info to have to read closely. A 10yo 800x600 monitor has oodles more resolution.

You actually will go blind

It's a fact-- the eyes suffer from the strain of over-focusing on small objects. The evolutionary niche they were intended to fill has a lot to do with macrospic vision for survelliance over things like plains and savannas, not 1600x1200 resolutions, normal or hd tv, newspapers, books or even parchment.

Near-sightedness, the inability to see things reasonably far away clearly, is an impairment that doesn't affect forty year olds nearly as much as it does the aggregate of society as they grow into young adulthood. The optical industry, as it sorts out new and better ways to make our eyes see more clearly, will tell you that as our society's moved toward mass literacy, eyesight on the whole has gotten poorer. Children from developing nations while endure eight hours of school a day with books, not em-radiating electronics. While the incidents of myopia are there, the frequency of it's occurence are much less.

"While fewer than one per cent of the Inuit and Pacific islanders had myopia early in the last century, these rates have since skyrocketed to as high as 50 per cent. These "overnight epidemics" have usually been blamed on the increase in reading following the sudden advent of literacy and compulsory schooling in these societies."

Starch and protein intakes may also be contributing factors in developing eyes.

The constant strain on the eye diminishes its abilities. The more mobile tech proliferates, the less time we spend not looking at news papers or screens or anything of the like. Our eyes didn't evolve for this type of high-focus miliage. Just keep that in mind. With glasses and contact lenses and LASIK, it seems that we'll be able to cope but take a moment to think about how much time you spend a day NOT reading (screen or print), NOT driving, NOT watching tv/gaming and NOT sleeping. If the answer's less than six hours, understand that means while our eyes developed to be open for about 18 hours and closed for six, without over-focusing, the way we live now could very much be taxing their original evolutionary mandate.

That is infact the concensus among optics proffesionals and academics and doctors. Those who read more fine print, such as that on small screens (or even small text on big screens), will effectively "train" their eyes to focus at that distance, and become essentially lazy. Could be mobiles, or books. That's what makes this headline nothing more than sensationalism at its finest. Bravo TechDirt. Another bit of tabloid mongering.

Re: combine

flexible displays

With any luck at all we will all have flexible displays in a couple years so mobile displays can be about four times the size and still fit in a cell phone too small to talk on comfortablly. I think both sony and palm have patents registered for rollable dislplays...
